* UNITED STATES MALCOLM K. GRAHAM, OF GRAHAM, TEXAS WINDOW VENTILATOR App1ication filed March 25, 1932. Serial No. 601,151.

The primary object of this invention is the provision of an economical, practical and durable window ventilator for use at the lower portion of a window opening so that 5 the outside fresh air may enter a sleeping porch or a bed-room in all weather conditions and in order that the wind may be deflected to prevent it blowing directly upon one in bed. The invention is also useful as a 19 ventilator in other exposed rooms as a protection from rain and to prevent papers, etc, on a desk or table from being disturbed.

The invention also provides a window ventilator of this character which may be placed in the window and removed easily for cleaning or in order that the sash can be closed completely when desired; or, while the ventilator is yet in the window opening, the sash can be lowered on the lower roller, thus ef- 90 fectually closing the opening without damage to the ventilator.

With the foregoing and other minor objects in View, the invention will be readily understood from a perusal ofthe following detailed description, taken in connection with the accompanying drawing, and in such drawing:

Figure 1 is a vertical sectional view of a portion of a window casing and sash and 11- lustrating an embodiment of one form of the invention.

Figure 2 is a view similar to that of Flgure 1, but with side walls added and snapped into operative position.

35 Figure 3 is a view similar to those of Figures 1 and 2, but with a screen wire curtain added and in operative position.

Figurel is a detail view of the flaps or side walls, showing the manner of their construc- 49 tion; and

Figure 5 is a detail view of the means employed for holding the screen wire to the curtain.

. Having a more detailed reference to the drawing, like numerals and characters designating like parts, and referring to Figure 1: 1 is the lower roller of the ventilator, which in the present instance is a pipe (or its equivalent) to provide sufficient weight and varying 59 in diameter with the thickness of the sash 5.

behind the dividing and guide strip. A heavy duck curtain 2 (or equal as to material) is securely attached to the pipe 1, rising at any desired angle, and greater than the net width of the window opening, to aid in shedding the 60 "water- An ordinary curtain rod 3 of metal with or without ornamental ends is also securely fastened to the curtain 2 in the manner shown in the drawing. A nail or screw 4 for supporting the rod 3, so that the pipe 1 barely reaches or touches the window, sill, is placed as shown. An ornamental metal bracket may be used instead of the nail or screw 4 in the event the window frame extends into the room too little to permit of obtaining the desired ventilation. These brackets, one on each side, will in this event support the ends of the rod 3. The brackets are alternative, however, and are not shown.

In Figure2is a modification of the ventilator by the addition of side flaps 7, these side walls or flaps being constructed by turning the corners 14 of the curtain under and back and sewing them in place to reinforce it," and then snapped onto the side wall ofthe window frame by snap fasteners 8. The upper edge of the side wall or flap is indicated at 9. The flap ends 15 are inserted, as shown by the dotted lines, in the pipe 1 and sewed across. ii

In Figure 3 is shown another alteration or modification of the ventilator, by the addition of a screen wire 12, the screen wire being secured toa rod 10 and to a rod 13. Small screws B on the window frame projecting through the flap support the rod 13. The rod 10 is then fastened by wire loops A or a similar means to the rod 3, the wire loops and parts being shown to better advantage in Figure 5. The screen wire may or may not'u9 be made a part of the ventilator as desired.

In constructing theflaps, see Figure 4:, they are so made that the least material is required, and when it is desirous of removing the ventilator, the side walls or flaps are un-? snapped and the ventilator lifted out, the flaps turned in on the curtain. In case the screen wire 12 is used, it is easily rolled up with the curtain on the rod.

5 The invention is susceptible to further ,1 i alterations and changes, such as would be within the scope and meaning of the appended claims.

What is claimed as new is:

, 1. Aventilator of the class described, comprising a body of flexible material and of a" width greater than the net width of awindow opening, a subtsantially heavy elongated member secured to the lower end of the ventilator body and made to lie between the window stool and window sash guide strip and on or slightly above the window sill; the upper end of the ventilator body having a rod or thelike secured thereto, said rod occupying a position sufliciently above the window stool to bring the.ventilator body on a slant or sloping. position in the window opening, the greater width causing the'sides of the ventilator to cup up and thus drain any falling water to the outside. i i

,2. A ventilator as claimed in claim 1, and including means for removably holding and supporting the ends of said rod immediately againstthe window frame inside a room,so

that'the ventilator body .lies wholly within .the'window opening and need not necessarily project outwardly inside the room.

I 3. 'A window ventilator of the class described, comprising a flexible body, a substantially heavy roller or. the like on the lower end of the-body, a supporting'rod or similar means on the upperend of said flexible body, and means carried on the inside of the window frame for supporting the ends of said rod,

40 the ventilator body being in a slanting position and wholly within the window opening if desired and held in atautened' position by saidheavy roller.

In testimony whereof I afix my signature.

MALCOLM K. GRAHAM.
